I bought one of these bags. Not the one that is shown but the one that is called "puppy purse' with mesh in the middle. I thought it was cute and then when I got it Mari would not have anything to do with it. Good luck trying to get all four legs in those holes. They can pull them out faster than you can get them all in. I got her in it one time then put it away and it was $$$ I learned a good lesson on that one.
I agree that they like their feet touching something. I have a little front pack now that she likes loves. She takes a nap in it at least once a day.
